Description

Technical Field

[0001] The utility model relates to the technical field of battery production and manufacturing, in particular to a square battery core positioning fixture. Background Art

[0002] The battery cells need to be fixed and positioned by a jig in one or several processes in the battery production and manufacturing process. The square battery cells of the same batch have the same size. In some processes, multiple square battery cells need to be fixed with different sides facing up (for example, one with the front wall or the rear wall facing up, one with the left wall or the right wall facing up, and one with the top wall or the bottom wall facing up). In this case, although the sizes of the multiple square battery cells are the same, three corresponding adaptive jigs still need to be customized. The existing square battery cell jigs need to be positioned by a cylinder or a motor as a power source. The structural compatibility range of this type of jig is small, which is about 50% of the maximum or minimum battery cell size. When the size range difference of the battery cell exceeds the compatible range, a new jig needs to be replaced. In actual production, the size of the battery cell is manufactured according to demand, that is, the size of the battery cell is different. Whenever the size of the battery cell exceeds the compatible range of the jig, a new jig needs to be customized and re-debugged. This method is obviously unreasonable in assembly line production, and there are problems of low production efficiency and increased production costs. Utility Model Content

[0003] The main purpose of the utility model is to provide a square battery core positioning fixture, aiming to solve the deficiencies mentioned in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes a square battery cell positioning fixture, comprising:

[0005] A base, wherein the base is provided with a first clamp, a second clamp and a third clamp for fixing the battery cell in sequence from left to right;

[0006] A first movable platform, wherein the first movable platform is movably mounted on the base and can perform left-right linear motion relative to the base, and can drive the first clamp and the second clamp to perform a clamping or loosening action synchronously during the left-right linear motion, so as to fix or loosen the square battery cell from the left and right directions, and a first locking structure is further provided for locking the first movable platform;

[0007] The second movable platform is movably mounted on the base and can make forward and backward linear motion relative to the base. During the forward and backward linear motion, the third clamp can be driven to clamp or release the third clamp to fix or release the square battery cell from the front and back directions. A second locking structure is also provided to lock the second movable platform.

[0008] The technical solution of the utility model sequentially arranges a first clamp, a second clamp and a third clamp on the base to realize the function of fixing three square battery cells at the same time, and a first movable platform and a second movable platform are movably arranged on the base respectively, and the first movable platform makes a left-right linear motion relative to the base to realize the synchronous clamping or loosening action of the first clamp and the second clamp, thereby fixing or loosening the square battery cell from the left-right direction, and the second movable platform makes a front-back linear motion to realize the clamping or loosening action of the third clamp, thereby fixing or loosening the square battery cell from the front-back direction, and the first movable platform and the second movable platform are locked respectively by the first locking structure and the second locking structure. When three square battery cells of the same size need to be fixed with different sides facing up, two of the square battery cells are fixed. The length range of the battery cells is the same, so the first movable table can drive the first clamp and the second clamp to move synchronously to position and clamp the two square battery cells based on the length of the square battery cells, and then lock them through the first locking structure. The remaining square battery cell can be driven by the second movable table to drive the third clamp to position and clamp it according to the situation, and then locked by the second locking structure. Compared with the traditional method, the positioning and fixing efficiency is fast, it can be applied to square battery cells of different sizes, and the compatible range is large, which can be 200% to 500% of the maximum or minimum square battery cell size. After the size of the square battery cell is changed, it can be clamped directly without debugging, avoiding the time and cost of frequent replacement of fixtures when there are many types of square battery cell sizes, effectively improving production efficiency and reducing production costs.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0015] The utility model provides a square battery core positioning fixture.

[0016] In the embodiment of the utility model, Figures 1 to 3 As shown, the square battery cell positioning fixture includes:

[0017] A base 1, wherein the base 1 is provided with a first clamp, a second clamp and a third clamp from left to right for fixing the square battery cell 100;

[0018] A first movable platform 11, which is movably mounted on the base 1 and can make a left-right linear motion relative to the base 1, and can drive the first clamp and the second clamp to synchronously clamp or release during the left-right linear motion, so as to fix or release the square battery cell 100 from the left and right directions, and a first locking structure is further provided for locking the first movable platform 11;

[0019] The second movable platform 12 is movably mounted on the base 1 and can make forward and backward linear motion relative to the base 1. In the process of making forward and backward linear motion, the third clamp can be driven to clamp or release, so as to fix or release the square battery cell 100 from the front and back directions. A second locking structure is also provided for locking the second movable platform 12.

[0020] The technical solution of the utility model sequentially arranges a first clamp, a second clamp and a third clamp on the base to realize the function of fixing three square battery cells at the same time, and a first movable platform and a second movable platform are movably arranged on the base respectively, and the first movable platform makes a left-right linear motion relative to the base to realize the synchronous clamping or loosening action of the first clamp and the second clamp, thereby fixing or loosening the square battery cell from the left-right direction, and the second movable platform makes a front-back linear motion to realize the clamping or loosening action of the third clamp, thereby fixing or loosening the square battery cell from the front-back direction, and the first movable platform and the second movable platform are locked respectively by the first locking structure and the second locking structure. When three square battery cells of the same size need to be fixed with different sides facing up, two of the square battery cells are fixed. The length range of the battery cells is the same, so the first movable table can drive the first clamp and the second clamp to move synchronously to position and clamp the two square battery cells based on the length of the square battery cells, and then lock them through the first locking structure. The remaining square battery cell can be driven by the second movable table to drive the third clamp to position and clamp it according to the situation, and then locked by the second locking structure. Compared with the traditional method, the positioning and fixing efficiency is fast, it can be applied to square battery cells of different sizes, and the compatible range is large, which can be 200% to 500% of the maximum or minimum square battery cell size. After the size of the square battery cell is changed, it can be clamped directly without debugging, avoiding the time and cost of frequent replacement of fixtures when there are many types of square battery cell sizes, effectively improving production efficiency and reducing production costs.

[0021] It is understandable that square cells produced in the same batch usually have the same size specifications. Therefore, when the utility model is used as a positioning fixture, in most cases, the square cells clamped and fixed have the same size specifications. Of course, the third clamp is designed independently of the first clamp and the second clamp, which allows the size specifications of the cell clamped by the third clamp to be different from those of the first clamp and the second clamp. Therefore, when there is a square cell with a different size specification, it can be clamped by the third clamp.

The base 1 is pivotally mounted with a screw 113 screwed to the first movable platform 11.
